我有一个web应用程序，它由两部分组成

1. Spring boot rest，服务器端端口8081
2. Vue vuex axios，端口8080上的前端

• 在我的Spring Boot应用程序下方

包com.example.googleoauth；

package com.example.googleoauth;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class GoogleoauthApplication {

    public static void main(String[] args) {
        SpringApplication.run(GoogleoauthApplication.class, args);
    }
}

package com.example.googleoauth.Controllers;

package com.example.googleoauth.Controllers;

import org.springframework.security.core.annotation.AuthenticationPrincipal;
import org.springframework.security.oauth2.core.user.OAuth2User;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.security.Principal;
import java.util.Map;

@RestController
@RequestMapping("/")
public class MainController {

    @GetMapping("/test")
    public String test() {
        return "Success test from Spring Boot";
    }

    @GetMapping("/login")
    public Map<String, Object> login(@AuthenticationPrincipal OAuth2User principal) throws IOException {
        return principal.getAttributes();
    }
}

包com.example.googleoauth.Configuration；

   package com.example.googleoauth.Configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.HttpStatusEntryPoint;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.CorsConfigurationSource;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;

import java.util.Arrays;

@Configuration
public class WebConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .cors().configurationSource(corsConfigurationSource())
                .and()
                .authorizeRequests(a -> a
                        .antMatchers("/", "/error", "/webjars/**", "/test").permitAll()
                        .anyRequest().authenticated()
                )
                .exceptionHandling(e -> e
                        .authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED))
                )
                .oauth2Login().defaultSuccessUrl("/login");
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("http://localhost:8080"));
        configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH", "OPTIONS"));
        configuration.setAllowCredentials(true);
        //the below three lines will add the relevant CORS response headers
        configuration.addAllowedOrigin("http://localhost:8080");
        configuration.addAllowedHeader("*");
        configuration.addAllowedMethod("*");
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

> < li>

我的Vue应用

 actions: {
 SIGNIN({commit}) {
     axios.get('http://localhost:8081/oauth2/authorization/google')
         .then((profile) => {
             commit('SET_AUTH_API', profile.data)
             return profile;
         })
         .catch((error) => {
             console.log(error)
             return error;
         })
 },

我可以访问http://localhost:8081/oauth 2/authorization/google，并使用Google成功进行身份验证，获取用户数据

但是我从端口8080通过Vue应用程序访问此链接时遇到问题，我在下面收到错误

在“中”访问XMLHttpRequesthttps://accounts.google.com/o/oauth2/v2/auth?response_type=code

在我向axios GET请求添加了标题：｛｝之后，这篇文章的回答对我有所帮助

在Chrome CORS扩展的帮助下，我摆脱了“已被CORS策略阻止”的消息，但当我发送时似乎什么都没有发生http://localhost:8081/oauth2/authorization/google“请求

    actions: {
    SIGNIN({commit}) {
        console.log("store-SIGNIN")
        const options = {
            method: 'GET',
            url: 'http://localhost:8081/oauth2/authorization/google',
            headers: {}
        };
        axios(options)
            .then((profile) => {
                // console.log(resp)
                console.log(1)
                commit('SET_AUTH_API', profile.data)
                console.log(2)
                return profile;
            })
            .catch((error) => {
                console.log(error)
                return error;
            })
    }

在我得到的开发控制台输出中

请给我指出正确的方向
